Watch Bands, Cases and Screen Protectors

Start with the watch: lug width, case size or model

This area is organized by the watch you own, so identify it first. Classic watches take bands measured by lug width, the gap between the lugs, commonly 20 mm or 22 mm; measure it with the old strap off. Smartwatch bands are listed by case size, such as 40, 44 or 45 mm, and by the watch generation. A band, a protective case and a screen protector are separate products, so check each one names your exact model.

Band materials, clasps and protection

Silicone and rubber bands shrug off sweat and water and suit sport, leather looks formal but should stay dry, stainless steel is durable and needs a tool to resize, and woven nylon is light and breathable. Clasps range from a tang buckle to a foldover clasp or a magnetic clasp that adjusts finely. Display cases and cabinets are sized by how many watches they hold. Chargers and docks are made for one watch family, so match the brand and generation.

Questions about Watch Bands, Cases and Screen Protectors

How do I measure lug width?

Take the old strap off and measure the gap between the lugs, the two prongs where the strap attaches, in millimeters. The new band's width at the lug end must match, and common sizes run in even steps such as 18, 20 and 22 mm.

Will a band for one smartwatch size fit all sizes?

Usually bands are sized by case family: a band for a 40 mm watch often fits other small cases from the same range, while 44 and 45 mm watches take the larger band. Always confirm the exact model range listed, because older and newer generations can use different lug shapes.

Is a silicone or leather band better for workouts?

Silicone or rubber suits workouts because it handles sweat, can be rinsed and dries quickly. Leather absorbs moisture and can stain or smell, so keep it for dry, everyday wear. Stainless steel works for both but is heavier and needs a tool to adjust the length.
